2 Claims. (Cl. -13) My invention relates to a combination sofa and bed, known as a davenport, and relates particularly to the frame construction and locking mechanism so that an accidental opening will not be effected. Applicant is the owner of United States Patent No. 2,710,411.

Heretofore, davenports having full size beds built therein, necessitated extra depth to accommodate said full size beds, and the mechanism for the operation of the folding mechanism. The extra depth entailed extra use of. materials for outer frame construction and extra materials for covering of the deeper sofa arms, as well as extra costs for labor entailed in building such deeper sofas.

It, therefore, is an object of my invention to provide in a davenport of conventional depth a full size bed eliminating extra materials in construction as well as the extra labor costs involved in building a deeper sofa.

Another object of my invention is.to provide a davenport having a full size bed built therein, the davenport to be of conventional outer appearance.

Another object of my invention is to provide a davenport having a full size bed built therein and the mechanism for the operation of the folding mechanism arranged to be supported and definitely positioned by levers and pivots so that the manipulation of the folding mechanism shall be smooth and free from binding or jamming.

Still another object of my invention is to provide a davenport with a full size bed built therein which is positively locked against unfolding, but which is readily and easily unfolded when properly manipulated.

Other objects of my invention are to provide an improved device of the character described, that is easily and economically produced, which is sturdy in construction, and which is highly eflicient in operation.

With the above and related objects in view, my invention consists in the details of construction and combination of parts, as will be more fully understood from the following description, when read in conjunction with the accompanying drawings in which:

Fig. 1 is a side elevational view of a davenport in open position.

Fig. 2 is a fragmentary elevational view of said davenport showing the foot section partially folded over.

Fig. 3 is an elevational view of said davenport with foot section completely folded over.

Fig. 4 is a side elevational view of said davenport with the folding portion in the completely closed position.

Fig. 5 is a fragmentary isometric view of the locking means in' the positions it assumes when the davenport is fully open as illustrated in Fig. 1.

Fig. 6 is a fragmentary isometric view of the locking means in the positions it assumes when the foot sections of the davenport are folded over as illustrated in Fig. 3.

Fig. 7 is a fragmentary isometric view of the locking means in the positions it assumes when the folding sections of the davenport are completely folded into the davenport frame.

Fig. 8 is a fragmentary isometric view of the locking member and support leg of the bed frame shown as they would be positioned when the bed is open or fully extended.

Fig. 9 is a fragmentary isometric view of the locking member and support leg of the bed frame shown as they would be positioned when the foot section of the bed is folded.

Fig. 10 is a sectional elevational view, taken from the longitudinal center line of the bed, showing a modified arrangement of the frame housing mechanism as it would appear when the bed is fully extended.

Fig. 11 is a sectional elevational view, taken from the longitudinal center line of the bed, showing a modified arrangement of the frame housing mechanism as it would appear when the folded bed frame is partially housed in the davenport frame.

Fig. 12 is a sectional elevational view, taken from the longitudinal center line of the bed, showing a modified arrangement of the bed frame housing mechanism as it would appear when the folded bed frame is completely housed on the davenport frame.

Referring now in greater detail to the drawings, wherein similar reference characters refer to similar parts, and also bearing in mind that the bed frame has similarly constructed parallel sides upon which a bed spring and supported mattress (not shown) are supported, I show a davenport having an outer frame section generally designated as A, and a bed frame having a head section generally designated as B, a body section generally designated as C, an intermediate or foot board supporting section generally designated as D, and a foot section generally designated as E; all of the aforementioned sections being articulated together and being adapted when open to lie in substantially co-planar relationship to serve as a bed, and when closed to serve as a resilient seat section for a sofa cushion.

It is to be noted that the outer frame section A is of conventional sofa frame construction having a back frame A1, arm frame members A2, and cross brace member A3. This outer frame may be made of any suitable material such as wood steel or aluminum.

Head section B of the bed frame consists of support member 14, made of steel angle which is connected to the outer frame A by a short arm 11 by means of a pivotal connection P1 to the end of support member 14, and whose other end is joined to approximately the center of cross member A3 of outer frame A by means of a pivoted connection P2. The support member 14 is also joined to the back rest frame A1 near its bottom by a long arm 10 whose one end is pivotally joined at P3 to support member 14 a distance approximately equal to the length of the short arm 11 along support member 14. The other end of long arm 10, is pivotally joined to back rest A1 at P4. The other end of support 14 is joined by means of a pivotedconnection P5 to support member 38 of the intermediate section C. A helical extension spring 16, whose function will be hereinafter explained, is connected between the bottom of outer frame A and short arm 11.

The body section C consists of a support member 38 made of angle iron whose length is substantially the same as the depth of the sofa and which is pivotally joined at P5 to support member 14 of head section as hereinbefore mentioned. The other end of support member 38 is pivotally joined at P7 to front board support section D. The body section C is provided with a leg 39 which is pivotally connected at P10 to support member 38 at about the midpoint of the entire bed frame to give greater rigidity and support to the bed frame.

A front board 45 is-fastened by a suitable means to a link 48 of a positioning linkage consisting of top' members 46, front board support member 48 and bottom member 50. Link 46 is pivotally connected at P16 to angle member 44 of the foot section E at one end while the other end is pivotally joined at P17 to one end of link-48 whose other endis pivotally connected at P18 to link 50 as well as front 'board positioning link 51 whose other end is pivotallyjoined at P19 to front board support 40. The other end of the positioning link 50 is joined pivotally to intermediate leg 39 at P21.

Foot section E consists of a substantially fiat angle section 44 pivotally connected to the intermediate section C at P20. Foot section E is'supported by the legmemher-43, sa'id legmember being pivotally'conneeted to the foot sectionat P11, a legactuating link-42 pivotally connected to the intermediate section D at P8 and 'tothe leg -member at P9. A locking member 43A is pivotally connected to the foot angle section '44 at P25, a locking member actuating link 4313 is pivotally connected to the intermediate section D at P8 and to the locking member support section D. Another keeper actuating lever 29 has one end pivotally joined at P14 to support member .114 while the other endof said keeper actuating lever '29 is pivotally connected to keeper hook 24 at P15.

The bottom portion of leg 39 is pivotally joined -at P22 to one end of a closing link 52 whose other end is pivotally joined at P23 to the short arm of an L-shaped closing mechanism or arm 26 which is pivotally joined at P24 at the vertex of the L to support member 38.

The end of the long .arm 26A of the closing mechanism arm 26 is so constructed that it will rotate and slide in a groove on the inner side .of the channel member 31 to permit the entire folded frame to move into the davenport frame A.

In Figs. 1 and 2, the .L-shaped closing mechanism-26 is adapted to slide into and out=of a groove (not shown) in the channel 31. The channel 31 is pivoted (not shown) to the frame so that the arm 26 may be extended .with'respect to the frame when the sections are extended to bedposition and the arm 26 is pushed within the channel 31 when the sections are contracted to vform a sofa.

Now when the bed frame is folded from the open position shown in Fig. 1, the foot section E is lifted to the position shown in detail in Fig. 2 whereupon the leg 43 is caused to fold over due to the action of the leg actuating link 42 and the foot section, through the pivots P9 and P11. At the same time that the folding action of the leg 43 takes place the locking member 43A is forced up into an angular position by the locking member actuating link 43B.

Further folding of the foot section E pushes forward the keeper hook actuating link 41 causing one end of keeper hook 24 to slide along guide slot 27 and because of the tendency of keeper actuating lever 29 to hold against lateral motion, the other end of keeper hook 24 rises in a vertical manner placing it in a position .to engage the laterally extending-lug 43C located atthe outer end of the locking member 43A.

It will be noted that in the arrangement of the foot section E support leg 43 and actuating link 42 as described above, all the mechanism extends a relatively shortdistance above the bed frame; in factthe top of the leg 43 and'the connected link 42 would all come well below the top of a mattress when the mattress is in place on the bed frame. ,This arrangement avoids one of the common complaints foundagainst prior artdevices.

It will also be noted that the arrangement of the locking hook 24 and connected-links 29 and 41 makes it possible to have these members located well below the top of the mattress when the bed is in the completely open position. The low position of these members is accomplished by providing the longitudinal movement of the pivot point P12 between the keeper hook 24 and keeper hook actuating link 41 in the slot 27 of the bed frame member 38.

The arrangement of the above described links and members so that they are well below the top of the mattress when the bed is fully extended avoids one of the more common complaints to prior art devices of this type.

The sections as folded are then lifted and forced into the davenport frame A as shown in Fig. 4. This brings into play the L-shaped closing mechanism 26 which pivots on the retaining member 31 to a position to locate the entire assembly within the davenport frame. As the assembly is positioned within the davenport frame the support member 14 of the head section B assumes a verticalposition by the action of the positioning arms 10 and 11; causing actuating link 29 to be forced forward and to rotate the keeper hook 24 on the pivot 12 and fold it down over the lug 43C on the locking member 43A and securely lock the entire assembly in the davenport frame.

The springs-36 and 15 react against each other so that there is a smooth continuity of motion of the assembly during the closing operation.

In the opening operation of the davenport bed the front board is raised and pulled forward and the reversal of the operations described above take place.

-In the modified embodiment shown in Figs. l0, l1, and 12 the bed frame L-shaped closing member 26A is definitely positioned during the bed closing or opening operation by the two links 31A.and 3113. The link 31A is pivotally connected to va support plate generally designated as P at a fixed pivot P30 and to the L-shaped closing member 26A at P31. The second link 31B is pivotally connected to the support plate P at P33 and to the L-shaped closing member 26A at P32. The length of the links is such that when the bed is in the extended erating to create a .definite support of the intermediate bed frame section C.

After the bed frame has been partially folded as illustrated in Figs. 2 and3, thewhole assembly is raised and forced into the bed frame as illustrated in Fig 11; throughout this operation, although the actuating force is exerted by the manipulator, the bed frame is at all times definitely positioned by the L-s'hapedclosing member 26A and its positioning links 31A and 31A.

In the final phase, the bed frame is definitely po9itioned within the davenport frame as illustrated in Fig. 12, the L-shaped closing member having traveled through a controlled arc of about During this closing operation of the mechansim illustrated in Figs. 10, 11 and 12 and similarly during the closing operation illustrated in Figs. 1, 2, and 3, the support leg 39 is folded so that it is parallel with the bed frame C when the bed frame is completely housed within the davenport frame A. This is accomplished by cooperation of the short arm of the L-shaped closing memher and the pivotally attached link 52.

It will be observed that in all phases of the closing and opening operation as illustrated in the modification shown in Figs. 10, l1, and 12, the bed frame is definitely positioned by the L-shaped closing member 26A and its positioning links 31A and 313. This arrangement precludes the possibility of binding or jamming of the bed frame sections B, C, D, and E in the davenport frame A during the opening and closing operation.

Although my invention has been described in considerable detail, such description is intended as being illustrative rather than limiting, since the invention may be variously embodied, and the scope of the invention is to be determined as claimed.

I claim as my invention:

1. A foldable bed frame for a sofa bed comprising head, body, intermediate, and foot sections pivotally connected in end to end relationship and adapted to be forwardly unfolded to a bed position wherein the sections are arranged in substantial coplanar relationship with the head and foot sections at the ends of the bed, the body section adjacent the head and the intermediate section adjacent the foot section and being adapted to be rearwardly folded to a seat position wherein the foot section forms a seat cushion support and is parallel to and spaced above said body section with said head section extending upwardly and at right angles to said body section, a substantially L-shaped leg pivoted intermediate its ends to the free end of said foot section, said foot section including a short arm which extends above and rearwardly along said bed frame when in bed position, means to opcrate said short arm, a locking member link having one end pivoted to said foot section and having a laterally extending bolt fixed to the free end of said locking member link, a locking member actuating link having one end pivoted intermediate the ends of said locking member link and the other end pivoted to said intermediate section, a first link having an end pivotally joined to said intermediate section and its other end pivotally joined to said leg above its pivot which is connected to the foot section, said intermediate section having a slot adjacent one end, a pusher bar having one end connected to said intermediate section and one end slid-able in said slot, a right angle keeper pivotally attached to said end of said pusher bar slidable in said slot, at second link having one end pivotally connected to said head section and the other end pivot-ally connected to said keeper whereby relative pivotal movement of said head and body sections will rock said keeper, said bolt being adapted to be hooked by said keeper when all of said sections are folded into sofa position in order to keep said foot section from accidentally moving upwardly when it forms the seat section of the sofa, said bolt being adapted to rest directly upon said body section to serve as a brace in order to prevent said foot section from moving downwardly against said body section when the sofa is formed, an L-shaped closing member pivotally mounted intermediate its end to said intermediate section, and the low er end of said L-shaped closing member being pivoted to one end of each of two links and the other end of each link having one end pivotally attached to said frame of said davenport.
